Description

Die Erfindung betrifft eine Zugtür für Industrieöfen, -wie Stahl- und Walzwerköfen, die mit allen Seitenrändern auf den Rahmen der Türöffnung aufliegt und so ihre Dichtung erhält. Bei den bekannten Türen dieser Art ist am Rahmen der Öfinung eine im wesentlichen waagerecht vorstehende Schaftplatte vorgesehen. auf der die Tür mit ihrer unteren Kante im geschlossenen Zustand aufliegt. Dadurch soll die Abdichtung des unteren Türrandes sowie eine Begrenzung der Türbewegung erreicht werden.The invention relates to a train door for industrial furnaces, such as steel and rolling mills, which rests with all side edges on the frame of the door opening and thus preserve her poetry. In the known doors of this type is on the frame Opening a substantially horizontally protruding shaft plate is provided. on which the door rests with its lower edge when closed. This is supposed to the sealing of the lower edge of the door and a limitation of the door movement achieved will.

Diese Abdichtung ist jedoch nicht immer zuverlässig, weil sich die Schaftplatte im Betrieb verwirft oder verbogen werden kann oder auch mit Zunder. Schlacke u. dgl. verunreinigt wird. Da nun aber eine ständig wiederholte Reinigung der Schaftplatte schwierig und zeitraubend ist, ist dieser geringfügig erscheinende :Mangel die L: rsache für eine unter Umständen ganz beträchtliche Verschlechterung des Ofenwirkungsgrades.However, this seal is not always reliable because the Shank plate can be warped or bent during operation or with scale. Slag and the like is contaminated. But now there is a constantly repeated cleaning the shaft plate is difficult and time consuming, this appears insignificant : Lack the cause of a possibly quite considerable deterioration the furnace efficiency.

Dieser Nachteil wird durch die Erfindung dadurch behoben, daß die Schaffplatte unterhalb der Tür stark. zweckmäßig unter dem Böschungswinkel von Asche und Schlacke, nach außen abgeschrägt und mit zwei oder mehreren schneidenförmigen Anschlagrippen versehen ist.This disadvantage is eliminated by the invention in that the Sheep plate below the door is strong. expediently at the angle of repose of ash and slag, bevelled outwards and with two or more blade-shaped Stop ribs is provided.

In dem Ausführungsbeispiel der Abb. i bis 3 ist eine Tür dargestellt, bestehend aus dem schrägen Türrahmen u, der wassergekühlten Tür b und der Schaffplatte c, deren waagerechte Arbeitsfläche d nur bis an die schräge Dichtungsfläche reicht und mit einem Ansatz e versehen ist, der die untere schräg liegende Abdichtung der entsprechend längeren Tür b und die Verlängerung der seitlichen und oberen Abdichtungsflächen des Türrahmens bildet, während die erforderliche Verlängerung f der Schatzplatte stark nach außen abgeschrägt und mit ebenfalls abgeschrägten schmalen und schneidenförmigen Anschlagrippen g für die Tür versehen ist. damit sich auch vor und neben der Tür keine Fremdkörper sammeln und die Abdichtung der Tür beeinträchtigen können.In the embodiment of Figs. I to 3, a door is shown, consisting of the inclined door frame u, the water-cooled door b and the sheep plate c, the horizontal working surface d of which only extends to the inclined sealing surface and is provided with an approach e, the lower inclined seal of the correspondingly longer door b and the extension of the lateral and upper sealing surfaces of the door frame forms, while the required extension f of the treasure plate strongly bevelled to the outside and with also beveled narrow and blade-shaped Stop ribs g is provided for the door. so that in front of and next to the door cannot collect foreign bodies and impair the sealing of the door.
